Ultradyne Ud Aluminum Rider 0.3lbs

The Ultradyne UD Aluminum Rider is a precision butt stock weight designed for shooters who demand enhanced balance and reduced felt recoil during extended shooting sessions. Built specifically to integrate with Ultradyne's UD Adjustable Butt Stock systems, this lightweight rider redistributes mass toward the rear of the platform, improving overall weapon stability and shooter control. Whether you're running a precision rifle setup or a tactical AR platform, adding stock-mounted weight is a proven method for minimizing muzzle rise and improving target reacquisition speed between shots.

Constructed from aluminum with a durable nitride finish, the Ultradyne UD Aluminum Rider delivers corrosion resistance and a professional matte-black aesthetic that complements modern tactical builds. At just 0.19 lbs actual weight, this component adds meaningful mass without creating unwieldy bulk—critical for maintaining ergonomics and maneuverability. The housing features two M-LOK slots, enabling modular attachment of rail sections, sling adapters, or auxiliary accessories directly to the butt stock for customized load-out configurations.

This weight rider is ideal for precision rifle competitors, tactical operators, and AR builders seeking to fine-tune their platform's balance and recoil signature. Installation is straightforward on any Ultradyne UD Adjustable Butt Stock; the rider mounts securely without tools or permanent modifications. Shooters who have invested in quality trigger work, muzzle devices, or optics will find that adding complementary weight to the rear stock creates a cohesive system that maximizes accuracy potential across multiple shooting disciplines.
